THOMAS LUCIEN TALIAFERRO, OF CHICAGO, ILLINOIS, ASSIGNOR TO PHOENIX- HERMETIC COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

COVER FOR JARS.

Application filed November 19, 1918. Serial No. 263,149.

To all whom it may concern Be it known that I, THOMAS LUCIEN TALIA- FERRO, a citizen of the United States, re-

-siding at Chicago, in the county of Cook,

State of Illinois, have invented certain new and useful Improvements in Covers for Jars, of which the following is a description, reference being had to the accompanymg drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in covers for jars, rand more particularly to a metal cover having a depending flange which is adapted to frictionally grip the outer wall of the jar for holding the cover in place thereon. L

Prior to my invention metal jar covers having a depending fia-nge formed with an inwardly projecting bead for gripping the outer wall of the jar have been made. It has been found in practice that it is difiicult to make jars in which the outer surface of the mouth of the jar is formed on a true circle without any irregularities in the shaping thereof. Often the outer wall of the jar in cross section is slightly elliptical. It is difficult to secure proper frictional grip between a cover of the type above referred to and a jar wherein the outer wall is irregular in contour. An object of the present invention is to provide a metal cover having gripping projections formed in the flange thereof, Whlch are so constructed as to grip the jar throughout a greater portion of its circular extent and which projections are so formed that each one may reshape itself to conform to anyirregularities in the contour of the jar and thus bring about an eiiicient frictional grip on the wall of the jar by each projection.

In the drawings which show by way of ,illustration one embodiment of the invention- Figure 1 is a view in side elevation showing the upper portion of a jar having my improved cover applied thereto;

Fig. 2 is anenlarged vertical sectional view through a portion of the same;

Fig. 3 is a similar View but showing one The invention is directed broadly to a metal cover for a jar, such as are used for i preserves, or the like, and which are preferably made of glass or some similar material. The jar has an outer vertical wall and a scat at the upper edge of the wall which is within the circular extent of the outer wall. The cover is preferably formed of a single piece of metal and has a depending flange which is provided with a series of inset portions parallel with the lower edge of the flange and are adapted to frictionally grip the outer wall of the jar to hold the cover in place. Belowthe inset portions the Specification of Letters Patent. lajgented June 14, 1921.

ening bead and the extreme lower edge of the flange is continuous and uniformly curved. These inset portions are spaced from each other a slight distance so that they are independent and each portion may bend or reshape itself independently of the others and thus the inset portions will conform to any irregularities in the contour of the outer wall and each portion will frictionally grip the jar and hold the cover in place.

Referring more in detail to the drawings, I have shown a portion of a jar at land this jar has an outer straight or vertical wall 2. rIhe up er edge of the wall terminates in a seat 3. y improved cover yfor/,the jar consists of a top section 4, which has-an integral depending iange 5. The extreme lower edge 6 of this iiange is continuous and uniformly curved. At the lower edge the flange is formed with a bead 7 which strengthens the lower edge of the flange and serves to preserve the circular shape thereof. The depending flange is formed with a series of inset portions 8, separated from each other by a straight section 9 of the ange, and these inset portions 8 are tapered inwardly from the lower edges thereof toward the upper edge thereof, so that each inset section has a gripping line l0 adjacent its upper edge. These inset por"ons are the only parts of the iiange which engage the outer wall 2 of the jar, as clearly shown in Figs. 2 and 3 of the drawings. he cover is so proportioned that in crowding the cover on to -the jar the-se inset portions will be slightly bent or reshaped so as to friction-k ally grip the jar. If the jar is out of roundthat is, slightly elliptical in cross section, then the projections which engage the jar at the maximum diameter of the jar will be bent or flattened to a greater extent, while possibly the inset portion at the minor diameter of the jar will only have a snug frictional grip on the wall of the jar with little or no bending or reshaping.

In Fig. 2 of the drawings, I have shown the grip of the inset portion on the jar with little or no reshaping of the same, while in Fig. 3 of the drawings, I have shown the inset portion as flattened to a considerable degree. Through this bending of the metal in each inset portion or ythe reshaping of the same, I have been able to construct a cover which will have a frictional grip on the outer wall of the jar throughout a greater portion of its circular extent, so that the cover will be held firmly in place. The sections 9 separating the inset portions are of only sufficient extent to permit the inset portions to bend or reshape themselves independently, as above noted, and, therefore, the cover grips the outer wall of the jar practically throughout its entire circular extent. This brings about a very efficient grip on the jar and holds the cover so firmly in place that a sealing ring may be used in Iconnection with the cover, if desired, and said sealin ring held firmly .seated on the jar.

In igs. 2 and 3 of the drawings, I have shown the top section of the cover as bent upwardly, as at 11, to form a groove on the inner face thereof for a sealing ring 12 which may be made of any desired composition which can be caused to adhere to the cover and secured thereto by slightly heating the same and applying pressure thereto. This sealing ring is adapted to engage the seat 3 at the upper edge of the wall of the jar and the cover will hold said sealing material pressed firmly against the seat 3 on the jar..

It is obvious that minor changes in the details of construction and the shaping of the parts ma be made without departing from the spir1t of the invention, as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A metal jar cover comprising a top section and a depending flange, said flange having inset portions at a distance above the lower edge of the flange for forming a relatively broad gripping contact with the jar walls throughout a greater portion of its circular extent, said inset portions being spaced sufliciently to permit the metal in each portion to bend or reshape itself independently of the other portions, so that the gripping surface of the cover may conform to irregularities in the surface or contour of the jar.

2. A metal ar cover comprising a top section and a depending flange, said ange having inset portions at a distance above the lower edge ofthe flange for gripping the jar throughout a greater portion of its circular extent, said inset portions being spaced sufficiently to permit the metal in each portion to bend or reshape itself independently of the other portions, so that the gripping surface of the cover may conform to irregularities in the surface or contour of the jar, said inset portions providing gripping surfaces continuous with the flange.

3. A metal jar cover comprising a top section and a depending Harige having a continuous lower edge, said flange having integral inset portions at a distance above the lower edge of the flange for gripping the jar throughout a greater portion of its circular extent, said inset portions being spaced sufficiently to permit the metal in each portion to bend or reshape itself independently of the other portions, so that the gripping surface of the cover may conform to irregularities in the surface or contour of the jar.

4. A metal jar Icomprising a top section and a depending flange, said flange having inset portions at a distance above the lower edge of the flange for gripping the j ar throughout a greater portion of its circular extent, said inset portions being spaced sufficiently to permit the metal in each portion to bend or reshape itself independently of the other portions, so that the gripping surface of the cover may conform to irregularities in the surface or contour of the jar, said inset portions providing gripping surfaces continuous with the walls of the flange, the lower edge of said flange having a bead formed therein for strengthening said edge.

5. A metal jar comprising a top section Y and a depending flange, said flange having inset portions integral with and at a distance above the lower edge of the flange for gripping the jar for a greater portion of its circular extent, said inset portions being spaced sufficiently to permit the metal in each portion to bend or reshape itself independently of the other portions, so that the gripping surface of the cover may conform edge of the flange comprising relatively long arcuate gripping surfaces spaced by relatively narrow flange walls whereby to providev a gripping Contact throughout the greater portion of the circular' extent of the jar wall, said inset portions being spaced suciently to permit the metal in each portion to bend or reshape itself independently of the other` portions so that the gripping surface of the cover may conform to the l0 irregularities in the surface or contour of the Jar.

In testimony whereof, I affix my signature.
